Account calls are used to create, search for, manage and delete Bits on the Run accounts. They can only be used by resellers. A reseller can manage an unlimited number of accounts.
Usage limits allow a reseller to limit the content and/or traffic usage for their accounts. This is useful in cases where individual accounts should not use too much (e.g. when a reseller sells $10/year packages to clients).
By default, an account can use an unlimited amount of content and traffic. Resellers can enable limits by setting the property usage_type to limited.
Note the limits act independently of the content/traffic limits of the reseller. Even if a reseller only has, say, 10GB traffic and 5GB content left, he can still give all his accounts terabytes of content and traffic. However, if the reseller gets blocked, the sub-accounts get blocked as well.
As API accounts calls contain security sensitive request and response parameters such as account key, secret, login and password, we are highly recommend to use HTTPS protocol for these calls. Preferably, request parameters should be send using POST method.
